The Web Stack Enterprise Manager (WSEM) has an informational section called the "Recent Alerts" section. The section displays various informational messages triggered from the server or the GUI.

The messages generated by the GUI are usually in response to an user action such as:

Clicking the start button for a server

Clicking 'Save' button on the properties page for a server configuration

The messages generated by the server are usually to indicate to the user that a state on the server backend has changed. These can include messages:

Indicating a server has started or it failed to start for some reason.

A new server was installed or removed from the system.

Another neat feature of the console is that it higlights the latest change in a specific alert color depending on the type of the alert. Hence if the change was informational in nature, you will see a olivish green highlight and for errors, it would be reddish with an error icon.

The following screencast displays the Recent Alerts section in action. Here are the steps that I follow in the screencast.

Stop the running Apache server

Start the stopped Apache server

Start the Lighttpd server which results in an error

Stop and start the Apache server from a terminal window

In this case the Recent Alerts section displays the messages that it receives from the backend server.
